Oprah’s new magazine landed on newsstands yesterday with a loud thud – it’s so heavy with ads.

The long-awaited debut issue of O, the Oprah Magazine produced by talk show queen Oprah Winfrey, weighed in at 320 pages, more than half of them – 166, to be precise – ad pages.

To most observers, it smacks of Good Housekeeping gone New Age, with a healthy dose of Reader’s Digest thrown in. The mag is largely inner-focused with articles such as “Make Your Dreams Come True: a Step-by-Step Planning Guide” and “How to Nourish Your Senses.”

There’s so much inner soul coverage, it looks like O is striving to be an antidote for the outward, appearance-focused Martha Stewart Living.

O is light on fashion and beauty, but when the mag does it, it is accessible and multicultural, with features such as “What to Wear With Jeans.”

The features will probably play better to Oprah’s fans in heartland America than to those in the cosmopolitan centers.

Much was made of the fact that Oprah pushed the table of contents right up front, to appear on page 2, so readers do not have to wade through pages of ads to find it.

But after the TOC, readers still have to fight their way through 50-odd pages before sinking their teeth into some real stories.

There’s little mistaking Oprah’s input.

Including the cover photo, there are 14 photos of Oprah in the issue – nine of them accompanying articles and five in ads. This is not a good idea because it could blur the separation of editorial and advertising.

The first real story doesn’t start until page 57. It’s a letter from Oprah called, “Let’s Talk,” which will be one of two regular Oprah-written articles in each issue. Of course, it has a picture of Oprah – just in case you couldn’t recognize her from the cover and the table of contents.

Three photos of Oprah accompany an interview with Camille Cosby in her first interview since the death of her son, Ennis. It’s Q&A format – but it’s a good Q&A. There are additional photos of the talk-show queen on page 261 and, of course, in the closing section, “What I Know for Sure” – also written by Oprah.

Naturally, the cover shot is Oprah. And she is likely to be the cover girl “for the foreseeable future,” O’s editor Ellen Kunes said.

We like the “Tap Your Personal Courage” calendar with inspirational quotes and ideas. It certainly beats Martha’s calendar for planting, trimming, cooking, gardening and planning things way, way, way in the future.

We’re less enamored with the charts where readers have to sit down and fill things out. That part may be well intentioned, but it seems too much like work. The magazine is distributing more than a million copies – nearly a 20 percent boost from its originally anticipated rollout of 800,000 copies.

“I think it is going to be a very big magazine – in the million to million and a half circulation eventually,” said Dan Brestle, president of Estee Lauder Cos., USA & Canada, who was one of the first advertisers to make a full year, six issue commitment to the title.
